A weakly compressible hybridizable discontinuous Galerkin formulation for fluid-structure interaction problems
Andrea La Spina, Martin Kronbichler, Matteo Giacomini +2
A scheme for the solution of fluid-structure interaction (FSI) problems with weakly compressible flows is proposed in this work. A novel hybridizable discontinuous Galerkin (HDG) m…
Numerical evidence of anomalous energy dissipation in incompressible Euler flows: Towards grid-converged results for the inviscid Taylor-Green problem
Niklas Fehn, Martin Kronbichler, Peter Munch +1
Providing evidence of finite-time singularities of the incompressible Euler equations in three space dimensions is still an unsolved problem. Likewise, the zeroth law of turbulence…
Modern discontinuous Galerkin methods for the simulation of transitional and turbulent flows in biomedical engineering: A comprehensive LES study of the FDA benchmark nozzle model
Niklas Fehn, Wolfgang A. Wall, Martin Kronbichler
This work uses high-order discontinuous Galerkin discretization techniques as a generic, parameter-free, and reliable tool to accurately predict transitional and turbulent flows th…
A matrix-free high-order discontinuous Galerkin compressible Navier-Stokes solver: A performance comparison of compressible and incompressible formulations for turbulent incompressible flows
Niklas Fehn, Wolfgang A. Wall, Martin Kronbichler
Both compressible and incompressible Navier-Stokes solvers can be used and are used to solve incompressible turbulent flow problems. In the compressible case, the Mach number is th…
Effective slip over partially filled microcavities and its possible failure
Zhouyang Ge, Hanna Holmgren, Martin Kronbichler +2
Motivated by the emerging applications of liquid-infused surfaces (LIS), we study the drag reduction and robustness of transverse flows over two-dimensional microcavities partially…
Efficiency of high-performance discontinuous Galerkin spectral element methods for under-resolved turbulent incompressible flows
Niklas Fehn, Wolfgang A. Wall, Martin Kronbichler
The present paper addresses the numerical solution of turbulent flows with high-order discontinuous Galerkin methods for discretizing the incompressible Navier-Stokes equations. Th…
Robust and efficient discontinuous Galerkin methods for under-resolved turbulent incompressible flows
Niklas Fehn, Wolfgang A Wall, Martin Kronbichler
We present a robust and accurate discretization approach for incompressible turbulent flows based on high-order discontinuous Galerkin methods. The DG discretization of the incompr…
Wall modeling via function enrichment: extension to detached-eddy simulation
Benjamin Krank, Martin Kronbichler, Wolfgang A. Wall
We extend the approach of wall modeling via function enrichment to detached-eddy simulation. The wall model aims at using coarse cells in the near-wall region by modeling the veloc…
A multiscale approach to hybrid RANS/LES wall modeling within a high-order discontinuous Galerkin scheme using function enrichment
Benjamin Krank, Martin Kronbichler, Wolfgang A. Wall
We present a novel approach to hybrid RANS/LES wall modeling based on function enrichment, which overcomes the common problem of the RANS-LES transition and enables coarse meshes n…
Wall modeling via function enrichment within a high-order DG method for RANS simulations of incompressible flow
Benjamin Krank, Martin Kronbichler, Wolfgang A. Wall
We present a novel approach to wall modeling for RANS within the discontinuous Galerkin method. Wall functions are not used to prescribe boundary conditions as usual but they are b…
